Ostara

Ostara Nutrient Recovery Technologies is a Vancouver-based company that extracts nutrients such as phosphorus and ammonia from waste water and waste solids – also known as sewage sludge. It then converts the nutrients into a slow-release, crystalline fertilizer called Crystal Green. The company has a facility in the City of York that provides services to more than 75,000 residents in York and five surrounding cities.

According to Ostara, Crystal Green fertilizer is “the world’s first renewable and environmentally safe fertilizer.” The company and product have been endorsed by Robert F. Kennedy, Jr., an environmental advocate and attorney.
